It is important not only to introduce the C4I(Command and Control, Communication, Computer, Intelligence) system for realizing the NCW(Network Centric Warfare) but also to evaluate the synergistic effect by the C4I system. However, the study effort for evaluating the system's synergistic effect is insufficient compared with introducing the system. Therefore, in this paper, we proposed a model that measures the synergistic effect of combat power by the warfare information system. To measure the synergistic effect of warfare information system, the network power must be considered, so we also proposed a new methodology for measurement of network power based on SNA(Social Network Analysis), not Metcalfe's law. A model we proposed is a model that measures the raised combat power by the network effectiveness. The methodology and model we proposed in this paper will be used usefully to analyze the practical effect of constructing future warfare information system.

The coupon issued by Korail (Korail's coupon) is characterized by the properties such as a discount rate, an issuing region, a selling region, and a practically discounted rate. The purpose of this study is to investigate their impacts on the redemption time using Log-Normal distribution, and to derive managerial implications for improving Korail's discount program. The result showed that the redemption time was shorter or longer depending a discount rate, an issuing region, a selling region, and a practically discounted rate.

As industires are evolving into a more advanced type industrial system, service economy has been more emphasized. But with the expansion of the service economy, the failure of the service has also increased. Customers flee caused by the service failure leads to from simple problems like financial loss to serious problems like damaging corporate image. Therefore, if possible, the system providing defect-free service should be established. If this is not possible, preventive measures should be taken in order to minimize the failure. The study as a tool to prevent service failure presents the concepts "service error matrix." And to confirm whether this idea is practical or not, this study investigated the hotel, one of the leading service industries, about actually occurring service failure and applied to service error matrix suggested in this study. Finally service blueprint and Poka-yoke are completed in order to reduce service failure of Y hotel which was the object of the interview for this study.

We first develop a value ecosystem framework to model the SDP(Service Delivery Process) of web services. Since the web service has been evolving from the basic web architecture (e.g., traditional world wide web) to a prosuming platform based on virtualization technologies, the proposed framework of the value ecosystem focuses on capturing the key characteristics of SDP in each type of web services. Even though they share the basic elements such as PP(Platform Provider), CA(Customization Agency) and user group, the SDP in the traditional web services (so-called Web1.0 in this paper) is quite different from the most recent one (so-called Web2.0). In our value ecosystem, users are uniformly distributed over (0, ), where ��represents the variety level of users' preference on the web service level. PP and CA provide a standard level of web service(s) and prosuming service package, respectively. CA in Web1.0 presents a standard customization package() at flat rate c, whereas PP and CA collaborate and provide customization service with a usage-based scheme. We employ a multi-stage game model to analyze and compare the SDPs in Web1.0 and Web2.0. Our findings through analysis and numerical simulations are as follows. First, the user group is consecutively segmented, and the pattern of the segmentations varies across Web1.0 and Web2.0. The standardized service level s (from PP) is higher in Web1.0, whereas the amount of information created in the value ecosystem is bigger in Web2.0. This indicates the role of CA would be increasingly critical in Web2.0: in particular, for fulfilling the needs of prosuming and service customization.

In this research, we have investigated the impact of servitization on firm value focused on Fortune 500 company's alliance announcement. The Firms are categorized to understand the impact of servitization and productization. The data includes Fortune 500 companies (2009, USA). Samples used for the hypothesis tests consist of 1,057 American companies that are opened on NYSE and NASDAQ, for the years 1990 through 2010. We test four research hypotheses based upon the various theoretical perspectives in servitization. The market is selective in reacting to alliance category; service company manufacturing company, service company service company. The findings show that alliance is significant between service company and manufacturing company. Also, the result shows significant relationship inter-service company's alliance. We have a significant relationship between company's alliance announcement and the market value of firms and shows significant AR in financial performance. Finally, this study presents implications for manufacturing companies that pursue service-led expansion as a strategic approach and are seeking to improve market value through alliance, partnership and cooperation. Continual effort must be placed to sustain market value of the firms.

In recent business environments, the competition among firms is shifting from the competition based on individual firm only to the competition based on alliance of firms. This is because it is not easy for a firm to perform all functions which consumers want. Thus, it is more effective to combine core competencies of different firms based on a strategic partnership. It is essential to establish a strategic partnership and this strategic partnership is a key success factor in PSS(Product-Service System) which combines products and services. In this paper, we propose a profit sharing model for PSS partnership. We first analyze customer's utility using Cobb-Douglas utility function and then propose the PSS profit sharing ratio considering functionalities and cost structures based on the combination ratio of PSS. This paper helps firms to develop partnership strategies for PSS.

The importance of service industries is growing as the portion of the service sector increases fast in the recent decades. This research deals with service prototyping and testing in a service laboratory. While products are generally tested through prototyping in new product development processes, services are difficult to test because of the characteristic of service, intangibility. A service laboratory, named s-Scape, is the experiment environment which has been developed to test services in virtual space for the purpose of analysis and improvement of real-world services such as hospitals and automobile show rooms. In this research, we present a service prototyping tool and language to support service test in the service laboratory. We first analyze key elements of service prototypes, and then design the service prototype diagram (SPD) and the service prototype description language (SPDL). SPD, which is a variant of the service blueprint, is a graphical tool to be used to generate SPDL. SPDL is an executable language of describing a service prototype of a real-world service in extensible markup language (XML) to experiment the service environment in virtual space. SPD reflects the control and interface of virtual reality devices, as well as key elements of service modeling. SPD represents a service process in which service providers and customers interact with each other in a service scape.

This study proposes a value based service design (VBSD) approach using Kano's model and QFD. Key quality factors and key cost factors are identified, evaluated and then incorporated to produce customer value index (CVI) and provider value index (PVI) which are together used to determine the four value strategy zones. Each value strategy zone suggests its own appropriate service development strategy based on its corresponding CVI and PVI characteristics such as maintaining current service, reducing costs, raising quality or eliminating/creating services. A camping car service design case is applied to this study, which shows the practical contribution of this VBSD approach.

There have been some research papers on financial services marketing, but there are only few exploratory studies that analyze characteristics of financial consumers in Korea. This study examines, based on FGI and web survey results, which factors consumers consider more important when choosing their financial services. I found that 'product profitability' is the most important factor when consumers choose their financial services, followed by 'relational benefits', 'convenience', 'product diversity', 'company stability', 'branch satisfaction', and 'social responsibility' in order of importance. The study also showed that there are differences in perception of these important factors depending on the types of consumers such as gender, age, size of financial assets, degree of risk-taking, and main financial company they are using. This study hopefully provide implications to marketing managers in financial services that they could decide which factors they have to focus on more when planning marketing strategies. Another objective of this study is to provide useful insights to the future researchers in financial services marketing.

In the marketing research area, service quality and customer satisfaction have been considered as ones of the most important marketing variables. However, there has been a lot of controversy over the direction of the casual relationship between the service quality and the customer satisfaction. The purpose of this study is to investigate the casual relationship between the service quality and the customer satisfaction. Granger's test of casuality method has been used to test the casuality relationship between two variables. In this paper, we applied the Granger's test of casuality method to KS-SQI and NCSI data of 17 business area which had been gathered annually. As the research result, we found that the customer satisfaction might cause the service quality in many service area.

As movie demands become more and more diversified, it is necessary for movie related firms to segment a whole heterogeneous market into a number of small homogeneous markets in order to identify the specific needs of consumer groups. Relevant market segmentation helps them to develop valuable offer to target segments through effective marketing planning. In this article, we introduce various segmentation methods and compare their advantages and disadvantages. In particular, we analyze "2009~2010 consumer survey data of Korean Film Industry" by using Latent Class Analysis(LCA), a statistical segmentation method which identifies exclusive set of latent classes based on consumers' responses to an observed categorical and numerical variables. It is applied PROC LCA, a new SAS procedure for conducting LCA and finally get the result of 11 distinctive clusters showing unique characteristics on their buying behaviors.

"Does CRM benefit affect repurchase or WOM? What is difference between VIP customers and non-VIP customers on CRM benefit?" is the interesting issue on premium industry such as a hotel business. This study examines how social benefit, psychological benefits, economic benefits and customization benefits affect repurchase and positive WOM in premium hotel. Only three of the four benefits showed significant results in repurchase and positive WOM. Also interactions between customer type and benefits were different in repurchase and WOM. The results figure out that VIP customers depend on psychological benefits and customization benefits on repurchase, whereas VIP customers depend on only social benefit on WOM. This finding suggests that hotels need to develop VIP program and approach differently to increase the repurchase volume or positive WOM effect.
